The MLO effect was measured with Mi 13 Pro and TP-LINK 7TR13090

What is MLO? I said that a year ago. How to check whether the router supports MLO, what kind of terminal supports what kind of MLO, has been explained a month ago.

How to check the wireless router support MLO type? Detail the types of MLO support from hardware and software

Now to test the effect of MLO, why now? Because only now can we meet the conditions for MLO to take effect. The ingredients for this dish are 7TR13090 and Mi 13 Pro.

Xiaomi 13 Pro has been bought for a year, erosion to Amma I recognize! The latest monthly update for my phone is 1.0.4.0UMBCNXM. Even if you are in this version, you may not be able to support MLO. Because of its push, it will not push the MLO driver to 100% of the users, so it is this version, but it does not necessarily have MLO driver support, that is, with the same handle, with the same machine, with the same life.

Xiaomi 13 Pro can support 2.4G+5G MLO, also supports dual 5G MLO, the current Wi-Fi 7 wireless router, as long as there is MLO option, you turn it on, and the two or three bands of MLO changed to the same name and password, but also the encryption method selected on WPA3, You can also use the WPA2/WPA3 coexistence option. Must use WPA3, must use WPA3, must use WPA3, since your SSID name and password changed to the same, and did not choose WPA3, also can not make MLO effective.

Everything's ready. How do we check if it's working? It's simple, check the connected frequency band in the background of the wireless router. Why don't you check it on your phone? Because the current rate does not have a superimposed sum, it is still 2882Mbps:

I said a year ago that MLO is a link aggregation action performed at the MAC layer, and it has only one IP address, and only one IP address is displayed in the background terminal list of the wireless router.

The following figure shows that the 7TR13090 uses only 2.4G+5G MLO, showing that there are two wireless bands connected to the Mi 13 Pro: 2.4G and 5G1

It also allows 5G1 and 5G2 to aggregate MLO:

Since the 7TR13090 is tri-frequency, it is possible to turn on MLO for all three frequencies. When the Mi 13 Pro connects it to open a three-band MLO, the phone is also dual 5G MLO. This tri-band Wi-Fi 7 equals simultaneous support for 2.4G+5G MLO, 5G1+5G2 MLO.

The Intel BE200 only supports 2.4G+5G MLO because it has only two wireless Macs, and the WCN7851 can support 5G1+5G2 MLO because it has three wireless Macs. Similarly, to see if the phone supports the 5G1+5G2 MLO, you need to see if it has removed one of the three Macs from the WCN7851. Mediatek and Broadcom I have not seen the world, no do not understand.

MLO requires driver support, as well as win11 system-specific support, which I also mentioned in the previous article. So far, the system can find support, but the wireless card driver is not supported, that is, the BE200 and WCN7851 do not have public driver support.

The following 7TR13090 10G network port is connected to the self-built speedtest speed measurement server, simple test several times, millet 13 Pro measured results are as follows:

I've done it so many times, I can't get to 3 gigabits. According to the theory, the single frequency 5G1 can reach 2300Mbps under 4096-QAM, and the single frequency 5G2 can also have 1100Mbps, which will add up to the limit of 3400Mbps, so that the upstream and downstream can not be reached. I guess it is the bottleneck of mobile phone speedtest speed measurement, is this self-built speedtest speed measurement program takes up a lot of CPU resources. This I understand very well, even the computer platform will have speedtest speed performance bottleneck, almost the CPU is not accurate. Let me put it another way. With Ixchariot, this speed measurement is less CPU-intensive, as long as no small packets are used.

The following is the result of the Mi 13 Pro streaming to the 5G of the 7TR13090, which reached 3228Mbps. MHM. That's the speed! It's pretty close to the limit. If I can be patient, keep adjusting the Angle and distance, take hundreds of tests, I should have better data.

2.4G +5G MLO I have said by a year ago, this is not practical, it is better not to use. The same is true of actual measurement, and it is slower than single-band 5G. It is really better not to use, so we do not have expectations for the MLO of the current dual-band Wi-Fi 7. 2.4G will obediently do smart home wireless connection point is OK. When you turned MLO on dual-band Wi-Fi 7, did it get worse?

MLO is the MAC layer of things, this is the protocol standard, there should not be compatibility problems, including 4096-QAM, but the standard things in the hands of people, there will always be a little thought to make their products more favorable.

Due to time constraints, next time take the Xiaomi 7000 to test the dual 5G MLO.

Unfortunately, Mi 13 Pro does not recognize 100 channels, otherwise I can try the effect of 160MHz+160MHz MLO...

I hope this article has given you some tentative understanding of MLO.
